COMBINATION vENTILATon AND CLEAN-OUT TEE.

Specification of Letters Patent.

Patented July 13, M915.

Application filed August 10, 1914. Serial No. 355,976.

To all whom it may concern:

Be it known that I, OTTO H. ROTERMUNDT, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Combination Ventilator and Clean-Out Tees, of which the following is a specification.

This invention relates to a combination ventilator and cleanout tee or elbow connection.

The object of the present invention is to provide a simple, substantial, easily installed fitting of the character described, through which the vertical and horizontal pipe con nections between a stove and chimney flue may be easily cleaned.

Another object of the invention is to provide said fitting or connection with a damper or ventilator, by which the draft in the stove may be regulated and the room ventilated.

Further objects will hereinafter appear.

The, invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings in which- Figure 1 is a side elevation of the device; Fig. 2 is a front elevation of same partly broken away.

A indicates a stove-pipe connection the upper end of which is closed by a suitable form of cover 2. The opposite right-angular extensions of the connection indicated at 3 and 4E, are adapted to be connected with the chimney flue and vertical section of the stove-pipe, not herein shown, in the usual manner. Suitably secured to the main section of the connection as indicated at 5 in a-position directly opposite to connection 3, is a rectangular shaped damper casing or extension 6, in which is pivotally mounted as at 7 a damper 8, to which a handle 9 is secured. The damper is mounted on a shaft 10, which extends into bearing extensions 11 formed on each side of the rectangular extension 6, and secured upon the shaft, within said extensions are collars 12, between which and the ends, coil springs 13 are positioned. The coil springs bear against the end of the bearings and the collars 12 and produce suflicient friction in this manner upon the collars to hold the damper in any position to which it may be adjusted by means of handle 9.

In operation, the connection or fitting here shown, may be attached to the chimney fine and stovepipe in the usual manner, and the draft of the stove may be easily regulated by damper 8. By opening this to a more or less extent, air is permitted to enter from the room in the direction of arrow a and en ter directly through connection 3 into the chimney flue. This will, to a more or less extent, destroy the draft through the stove, and the draft through the stove can in this manner be regulated by damper 8. The damper 8 not only serves the purpose of regulating the draft through the stove, but also acts as a ventilator through which the upper layers of foul air Within the room may be withdrawn. Constant ventilation or circulation of air is thus maintained in the room.

The connection or fitting constructed as here shown also serves as a cleanout. The horizontal connection 3 may be cleaned by opening damper 8, while the vertical stovepipe connections may be cleaned by removing cover 2.

The materials and finish of the several parts of the connection here shown, are such as the judgment and the experience of the manufacturers may dictate.

Having thus described my invention, what I claim and desire by Letters Patent, is-

1. The combination with a T-shaped stovepipe connection of the character described, of an open-ended extension formed on one side of the connection, a damper mounted in said extension, means for adjusting and maintaining the position of said damper, said means comprising a shaft upon which the damper is secured, bearings for said shaft having enlarged chambers formed therein, coil springs surrounding the shaft in said chambers, and collars secured on the shaft against which the springs bear.

2. As a new article of manufacture, a flue fitting for forming a union between a vertical stove pipe and the chimney flue composed of a short vertical section of pipe the lower end of which is adapted for connection with the top end of the stove pipe and the upper end of which has a cover, and a lateral extension between the ends of the vertical section and spaced from the cover and adapted for connection with the chimney flue, said vertical pipe having a damper controlled inlet which is in horizontal alinement with said lateral extension, and said cover serving as a cover for the top end of the stove pipe and being removable so that by closing of the damper and removal of the cover the entire vertical section may be cleaned.

3. A device of the class described comprising a vertical pipe, an open ended extension carried by the pipe, oppositely disposed bearings carried by the extension, springs in the bearings, a shaft having its ends extended into the bearings, and abutments fixed adjacent the ends of the shaft and engaged by the said springs, a damper fixed to the shaft, and means carried by the damper for swinging the same outwardly to close the open end of the extension or inwardly to vary the ingress of air through the extension to the pipe, said springs serving to hold the damper in its closed or adjusted positions.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
